Stephen Curry lamented a "perfect storm" as the Golden State Warriors were on the end of a 140-88 defeat to the Boston Celtics on Sunday.
The loss at TD Garden was the fourth-worst the Warriors, who entered the contest in good form, have suffered in franchise history.
It marks the third time this season the Celtics have won by 50 points or more, meanwhile, as they racked up an 11th victory in a row.
"The way that they've been playing, they seem very sure of themselves in their identity and who they are," Curry said. "Give them credit.
"They came out and whooped us from the jump, and it was a perfect storm of a rough [day] on our end and them taking it to us."
Curry played despite being questionable, but he did not feature in the second half as he finished with a season-low tally of four points.
The Warriors will hope to have Curry back to full fitness for their return to action against the Milwaukee Bucks on Wednesday.
"This was not a day off for Steph, though he probably could have used one," Warriors head coach Steve Kerr said.
"He's played so well and for so long this year. Hopefully the next few days he'll get it recharged."
Jaylen Brown led the scoring with 29 points, while birthday boy Jayson Tatum had 26 in the Celtics' third-biggest victory in franchise history.
Boston led by a franchise-record 44 points at the midway point and went on to extend their advantage to 51 before making some changes.
"It feels great, but, at the same time, it's always within humility," Brown said. "We don't take the game for granted.
"We didn't come and mess around and that's just how we show our respect to the game, we handle business and take care of it.
"It's a lot of respect for the Golden State Warriors, but we feel like it's our time now."
The 48-12 Celtics lead the Eastern Conference, while the Warriors are ninth in the Western Conference with a record of 32-28.
